Because of who he is and what he’s done, Jerry Sandusky could be in particular danger of sexual assault when he is sent off to prison this week.

With thousands of inmates raped behind bars in the U.S. each year, statistics compiled by the federal government show that sex offenders are roughly two to four times more likely than other inmates to fall victim.

Sandusky, the 68-year-old former Penn State assistant football coach, will be sentenced today for sexually abusing 10 boys in a scandal that rocked the university and brought down coach Joe Paterno. Sandusky is likely to spend the rest of his life in prison.
